I have to wonder what the supposed Saudi/Russian investors who helped back his bid are thinking right now. While the site hasn't imploded quite yet, Trump returning caused a noticeable exodus of users. Some big accounts like Seth Abramson have reported their follower counts dropped by about 3% since, presumably from people quitting and deleting their accounts over it. I can't see the site having done another banwave on bots with no staff to conduct it, anyway.
While the investors might share Elon's vision, they can't reasonably be onboard with sinking billions into buying the site then destroying what profitability it had. And it's not like those users leaving are going to be replaced by an equal wave of conservatives joining up to follow Trump or other banned conservative accounts.
Ye must be furious though, since these changes effectively make Parler nearly worthless.
